An open-label, two-part study to determine the absolute bioavailability (BA) of OZ439 using simultaneous intravenous [14C] OZ439 microdose/800 mg oral dosing and to investigate the pharmacokinetics (PK) of OZ439 granules administered as single doses suspended in different volumes and when co-administered with a single dose of Cobicistat, a string CYP3A4 inhibitor, to healthy subjects in fasted state

Part 1:The purpose of Part 1 of the study is to investigate how much of the OZ439 compound is absorbed into, distributed in, and eliminated from the body (this is called pharmacokinetics) when administered orally as compared to an intravenous (iv;…
